Assertion (A) : Energy pyramid is slopping. Reason (R ) : The energy of one trophic level is lower than another level as we go up.

Energy transferred from one trophic level to another is

Loss of energy from one trophic level to next higher trophic level is

The flow of energy along various trophic levels of an ecosystem is :

Food chains and the energy flow within an ecosystem provide an important understanding of contingencies and mutual dependencies of organisms. The given below flow chart depicts the energy flow within some members of a grassland ecosystem. The grass in the below ecosystem transducer 120,000 J of sunlight and fixes it into 12,000 J of energy. It is established that 90% of the energy of one trophic level is not passed to the next trophic level. Further assume that the energy transferred from one trophic level to the next is equally shared among the different organisms at that trophic level. Based on the above information, indicate the amount of energy that an organism C may have received from an organism from the previous trophic level.
